Should have added IANAL, so any inaccuracies are definitely introduced by my layman's explanation.

What nuances are left then? What small amount of hope can be gleaned from the ruling?

[airstrike]

Specifically, POTUS has absolute immunity from criminal prosecution for actions that are within their constitutional authority, presumptive immunity from all official acts (but not absolute), and no immunity from unofficial, private acts committed by the president.

Congress could also pass legislature or constitutional amendments to revert the effect of that tragic decision, though of course those also come with their own sets of challenges.

(IANALE btw)

Congress can pass whatever, but POTUS would still have to sign it. Even this Congress is not veto proof

[airstrike]

A future POTUS might be willing to sign it, though yeah, it doesn't help with the current situation. That would still need to be artfully litigated.
